^^ Yup, that was exactly my conclusion.
Since the Kevlar didn't give, the frame took all of the main string impact as opposed to a normal string which would stretch and absorb some of the impact.
In addition the crosses would wear paper thing and snap about half the time, letting the Kevlar just flop around.
In my best estimate, when I hit flatter, the Kevlar mains would break, when I hit with more spin the ALU crosses would break.
Except for the one amazing double string break.
You either die a hero or live long enough to see yourself become the villain.
